CompTIA A+ Core 1 (220-1201) — Question 160

Which of the following network technologies is used for the operation of physical access control systems?

Answer options

• A. 802.1Х
• B. VPN
• C. GPS
• D. RFID

Correct answer: D

Explanation

RFID (Radio Frequency Identification) is the correct answer because it is specifically designed for identification and tracking through radio waves, making it ideal for physical access control systems. In contrast, 802.1X is a network access control standard, VPN is used for secure remote access, and GPS is for location tracking, none of which are directly related to physical access management.
